Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Betätigung eines Teiles eines Werkzeuges od.dgl., insbesondere einer Schreibmine zwecks Ein- und Ausfah­rens aus einem Schreibgerät aber auch eines Schrauben­ziehers, der in einem Handgriff lösbar befestigt ist.The invention relates to a device for actuating a part of a tool or the like. In particular a writing lead for the purpose of retracting and exiting a writing instrument but also a screwdriver which is detachably fastened in a handle.

Es ist bekannt, eine Schreibmine in einem Gehäuse so anzuordnen, daß die Schreibmine eingefahren und aus­gefahren werden kann. Hierzu befindet sich an dem Schreib­gerät an dem der Spitze gegenüberliegenden Ende ein Betä­tigungsteil, der durch eine Dreh- oder Schubbewegung die Schreibmine ausfährt oder auf Grund einer vorhandenen Fe­der in die eingefahrene Lage zurückschnellen läßt. Derar­tige Mechanismen sind jedoch verhältnismäßig kompliziert. Zum einen müssen mehrere Teile durch unterschiedliche Fer­tigungen hergestellt werden und zusammengesetzt werden. Zum anderen nutzen sich die Teile bei ständiger Betätigung ab, so daß der Gebrauchswert des Schreibgeräts darunter leidet.It is known to arrange a writing lead in a housing so that the writing lead can be retracted and extended. For this purpose, there is an actuating part on the writing instrument at the end opposite the tip, which extends the writing lead by a rotating or pushing movement or can snap back into the retracted position due to an existing spring. However, such mechanisms are relatively complicated. On the one hand, several parts have to be manufactured and put together by different productions. On the other hand, the parts wear out with constant actuation, so that the use value of the writing instrument suffers.

Es gibt auch Halterungen für Werkzeuge, beispiels­weise Schraubenzieher, die mit Hilfe ihres Schaftes in eine Steckhülse eingesetzt werden und mit Hilfe eines Mechanismus aus diesem Reibungssitz entfernt werden kön­nen. Auch hier handelt es sich um komplizierte und stör­anfällige Teile.There are also holders for tools, for example screwdrivers, which are inserted into a receptacle by means of their shank and can be removed from this friction fit by means of a mechanism. Here too, the parts are complicated and prone to failure.

Der Erfindung liegt das Problem zugrunde, eine Betä­tigungsvorrichtung der eingangs gennanten Art mit einfa­chen Mitteln zu bewerkstelligen. Erreicht wird dies durch die in den Ansprüchen angegebenen Merkmale.The invention is based on the problem of accomplishing an actuating device of the type mentioned at the beginning with simple means. This is achieved by the features specified in the claims.

Die Erfindung beruht im Prinzip darauf, daß ein exzentrisch angeordneter Teil, ein Schwenkhebel oder ein Nockenelement auf das hintere Ende des Werkzeugs einwirkt. Es ist lediglich notwendig, diesen exzentri­schen Teil oder Hebel zu verschwenken, um eine Verände­rung der Lage des Werkzeuges herbeizuführen.The invention is based in principle on the fact that an eccentrically arranged part, a pivot lever or a cam element acts on the rear end of the tool. It is only necessary to pivot this eccentric part or lever to bring about a change in the position of the tool.

Die Erfindung wird nachstehend an Hand der Zeich­nung beispielsweise erläutert.

  • Fig. 1 zeigt eine Betätigungsvorrichtung für ein Schreibgerät gemäß der Erfindung in Drauf­sicht.
  • Fig. 2 zeigt eine Seitenansicht der in Fig. 1 ge­zeigten Vorrichtung.
  • Die Fig. 3 bis 5 zeigen andere Ausführungsformen der in der Betätigungsvorrichtung verwend­baren exzentrischen Teile.
The invention is explained below with reference to the drawing, for example.
  • Fig. 1 shows an actuating device for a writing instrument according to the invention in plan view.
  • FIG. 2 shows a side view of the device shown in FIG. 1.
  • 3 to 5 show other embodiments of the eccentric parts that can be used in the actuating device.

In den Fig. 1 und 2 ist mit 10 ein Schreibgerät bezeichnet, welches im wesentlichen eine zylindrische Form aufweist. Am vorderen Ende ist eine Öffnung vorge­sehen, so daß eine Schreibmine 11 ausgefahren bzw. ein­gefahren werden kann. Die Fig. 1 zeigt die eingefahrene Lage der Schreibmine 11, die Fig. 2 die ausgefahrene Lage, in welcher das Gerät zum Schreiben verwendet wer­den kann. Es ist eine Feder 20 schematisch wiedergege­ben, welche die Schreibmine in die eingefahrene Lage vorspannt.1 and 2, 10 denotes a writing instrument which has a substantially cylindrical shape. An opening is provided at the front end so that a writing lead 11 can be extended or retracted. FIG. 1 shows the retracted position of the writing lead 11, FIG. 2 shows the extended position Location in which the device can be used for writing. A spring 20 is shown schematically, which prestresses the writing lead in the retracted position.

An dem der Schreibspitze gegenüberliegenden Ende des Schreibgerätes 10 ist eine Ausnehmung 13 vorgesehen. Es handelt sich hierbei um einen schlitzartigen Durch­bruch durch das Schreibgerät 10. In diesem Durchbruch befindet sich ein Exzenter 12, welcher mit Hilfe eines Stiftes 14 um diesen Stift drehbar im Schlitz 13 ange­ordnet ist. Der Exzenter 12 steht mit seinem Außenum­fang mit dem der Schreibspitze gegenüberliegenden Ende der Schreibmine 11 in Eingriff, wobei dieser Eingriff über die Feder bewerkstelligt wird.At the end of the writing instrument 10 opposite the writing tip, a recess 13 is provided. It is a slit-like opening through the writing instrument 10. In this opening there is an eccentric 12 which is arranged in the slot 13 by means of a pin 14 so as to be rotatable about this pin. The outer circumference of the eccentric 12 is in engagement with the end of the writing lead 11 opposite the writing tip, this engagement being brought about by the spring.

In der in Fig. 1 gezeigten Lage ist die Schreib­mine 11 eingefahren und berüht diejenigen Teile des Exzenters 12, die eine geringe Radialersteckung haben.In the position shown in Fig. 1, the writing lead 11 is retracted and touches those parts of the eccentric 12 which have a low radial extent.

In Fig. 2 ist die Schreibmine ausgefahren und das hintere Ende der Schreibmine ist mit den Teilen des Exzenters 12 in Berührung, die eine große Radialersteckung in bezug auf den Schwenkstift 14 haben. Es ist ersicht­lich, daß das Ein- und Ausfahren dadurch bewerkstelligt werden kann, daß der Exzenter 12 um seinen Schwenkstift 14 verschwenkt wird.2, the writing lead is extended and the rear end of the writing lead is in contact with the parts of the eccentric 12 which have a large radial extension with respect to the pivot pin 14. It can be seen that the retraction and extension can be accomplished in that the eccentric 12 is pivoted about its pivot pin 14.

Die Fig. 3 und 4 zeigen eine abgewandelte Ausfüh­rungsform im Hinblick auf die Fig. 1 und 2. Bei dieser Art der Realisierung der Erfindung ist an der Achse 14 bzw. an dem Exzenter 12 ein Clip 15 befestigt, welcher dazu verwendet werden kann, das Schreibgerät 10 in einer Tasche eines Jacketts zu befestigen. Die in den Fig. 3 und 4 gezeigten Lagen entsprechen dabei der in der Fig. 2 gezeigten Lage der Schreibmine 11, d.h. es ist die ausgefahrene Lage für einen Schreibvorgang gezeigt. Wird nun der Exzenter 12 um seine Achse 14 (bei Blickrichtung der Fig. 3) verschwenkt, so wird auch der Clip 15 ver­ schwenkt, so daß er nicht wie in Fig. 3 gezeigt nach links sondern nach rechts zeigt. Er befindet sich in dieser Lage in unmittelbarer Nähe zum Außenumfang des Schreibgeräts 10 und kann daher seiner Funktion als Be­festigungsteil an der Tasche eines Kleidungsstücks gerecht werden.3 and 4 show a modified embodiment with regard to FIGS. 1 and 2. In this type of implementation of the invention, a clip 15 is fastened to the axis 14 or to the eccentric 12, which clip can be used to To attach the writing instrument 10 in a pocket of a jacket. The positions shown in FIGS. 3 and 4 correspond to the position of the writing lead 11 shown in FIG. 2, ie the extended position for a writing operation is shown. If the eccentric 12 is now pivoted about its axis 14 (when looking in FIG. 3), the clip 15 is also ver pivots so that it does not point to the left as shown in Fig. 3 but to the right. In this position, it is located in the immediate vicinity of the outer circumference of the writing instrument 10 and can therefore fulfill its function as a fastening part on the pocket of a piece of clothing.

In Fig. 5 ist eine andere Ausführungsform des Exzenters gezeigt, und zwar befindet sich bei dieser Ausführungsform in dem Durchbruch 12 des Schreibgerätes ein Schwenkhebel 21. Dieser ist mit Hilfe eines Schwenk­zapfens 14 verschwenkbar. Der Hebel hat zwei sich in radialer Richtung unterschiedlichweit ersteckende Bereiche. In der in Fig. 5 gezeigten Lage befindet sich das hin­tere Ende der Schreibmine 11 in Eingriff mit dem Bereich des Hebels 21 mit geringer Radialerstreckung. Wird der Hebel 21 bei Betrachtung der Fig. 5 in Gegenuhrzeiger­richtung verschwenkt, so bewegt sich die Schreibmine nach links, bis sie mit einem Bereich des Hebels 21 in Eingriff gelangt, der einen großen radialen Abstand zum Schwenkpunkt 14 hat. In Fig. 5 ist entsprechend die eingefahrene Lage der Schreibmine gezeigt, nach Durch­führung des erwähnten Schwenkvorganges befindet sich die Schreibmine 11 dann in ausgefahrener Lage.5 shows another embodiment of the eccentric, and in this embodiment there is a pivot lever 21 in the opening 12 of the writing instrument. This can be pivoted with the aid of a pivot pin 14. The lever has two areas that extend in the radial direction to different extents. In the position shown in FIG. 5, the rear end of the writing lead 11 is in engagement with the region of the lever 21 with a small radial extent. If the lever 21 is pivoted in the counterclockwise direction when viewing FIG. 5, the writing lead moves to the left until it engages with an area of the lever 21 which is at a large radial distance from the pivot point 14. 5 shows the retracted position of the writing refill accordingly. After the pivoting operation mentioned has been carried out, the writing refill 11 is then in the extended position.

Die Teile 12, 14, 15 und 21 können aus Kunststoff hergestellt werden, es handelt sich dann um einfach herstellbare Spritzartikel, die auf einfache Art und Weise in der Ausnehmung 13 des Schreibgerätes angeordnet werden können.The parts 12, 14, 15 and 21 can be made of plastic, it is then easy to manufacture molded articles that can be easily arranged in the recess 13 of the writing instrument.
